WIND-WHEEL.

SPECIFICATION forming part of Letters Patent No. 571,056, dated November 10, 1896. Appli ation filed June 19, 1896. Serial No. 596,204. (No model.)

To all whom it may concern.-

Be it known that I, J OHN LINDSAY THOMP- SON, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Wind-Vvheels, of which the following is a specification.

My invention relates to improvements in wind-wheels of the horizontal type; and it consists in the novel features of construction hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of the wind-wheel embodying my 1 5 invention, showing the vertical shaft on which it is mounted broken off; and Fig. 2, a plan of the same, the arrows showing, respectively, the direction in which the wheel is rotating and that of the wind or turning force. Both these views show the wheel as it appears in motion.

arepresents the vertical shaft adapted to be mounted on a staff, mast, barn, tower, or elsewhere to suit the surroundings or the work to be performed by the wheel, which latter is suitably mounted on said shaft and is composed of the elements thatIwill now describe. I) b are flanged hubs keyed to shaft a at a suitable distance apart at its top or upper 0 end, a 0 o c radial eyes constructed on said hubs, and d d d cl horizontal V-shape brackets or open frames comprising tangential rods or arms whose inner diverging ends engage the eyes 0' and are detachably connected 3 5 thereto by means of nuts and whose outer converging ends engage eyes d on the coupling and reinforce plates (J, and are also detachably secured by means of nuts.

e e e 6 represent segmentalrim-sections de- 0 tachably connected together (to form a continuous circular series or a rim) by means of the coupling-plates O and bolts 0.

e represent angular bends or recesses in said rim-segments e to form receptacles for the 5 free ends 1 of the blades or fan-paddles B when thrown open. The blades B are pivoted or hinged to the rim-segments e by means of pins 10 and plates or brackets 19 2, and the outer ends B of said blades are curved or flared toward the wind, the pivotal end of each blade being notched or open-slotted at B for the free outward swinging or full and free clearing of the curved portion B beyond the rim 6.

The arrow A indicates the direction in which the wind is advancing and entering into the wheel, and arrow D the direction in which the wheel revolves.

The wheel as constructed and being of the horizontal class may be mounted 011 a tower, barn, or building, as stated, or on a separate mast separate from any structure, and readily connected with a well or pump or other object to be driven, either directly or by means of a horizontal shaft mitered to the vertical shaft, on which latter the wheel is rigidly secured or mounted by keys or otherwise, as hereinbefore mentioned.

The wheel being composed of the elements named, which are detachably connected or united together, is thus a knockdownone, conveniently capable of very ready handling at all times, and of being packed in small compass for storing and shipping, and also for making repairs at a minimum of expense, as any part or section can be replaced or handled without disturbing the rest.

In the operation of the wheel (which is clearly seen in the several views) the blades are so mounted and they clear so quickly that they get the full force of the wind or other propelling medium, which is duly utilized, andn'o lost motion nor dead wind or force occurs in their use. B of the blades present afinal face 01' resistance to the wind as the wheel advances, and after said wind has spent its direct force on the face of a blade this curved end serves to cause the blade to open more quickly and to readily bring it into rest against the receptacled rim.

I claim- 1. A knockdown horizontalv wind-wheel composed of a pair of hubs keyed to a vertical shaft; a series of horizontal V-shape brackets or open, skeleton rod-frames detachably secured at their inner, divergent ends to said hubs; a series of segmental rim sections having receptacles or bent, recessed portions made therein and detachably jointed together in a circle, and detachably mounted, also, at the outer, convergent ends of said The curved pivotal ends V-brackets and a series of blades or fan-paddles pivotally mounted on said segmental rimseetions; substantially as herein set forth.

2. In a horizontal wind-Wheel, a blade or fan-paddle composed of a plate having its outer pivotal or hinged end curved or flared toward the Wind, whereby a prolonged impingement of the Wind, and a ready, quick opening or clearing of the blade against the Wheel-rim are effected in the revolutions of [o the wheel, substantially as herein set forth.

In testimony of which invention I have hereunto set my hand.

JOHN LINDSAY THOMPSON.
